Central or Primary Hypothyroidism? How to Differentiate in Patients with Low T4 but Mildly Elevated TSH Levels

Turan Serap , Gurbanov Ziya , Bas Serpil , Abali Saygin , Atay Zeynep , Bereket Abdullah

Background: Central hypothyroidism (CH) is caused by TSH and/or TRH deficiency leading to hypothyroxinemia with low, normal or mildly elevated TSH levels. Differentiation of CH with mildly elevated TSH levels from primary hypothyroidism (PH) can be difficult. However, this differentiation has important clinical implications (i.e. cortisol replacement before L-thyroxine).Objective and hypotheses: In this study, we constructed a nomogram all...

Evaluation of Renal Functions in Obese Children and Adolescents with Cystatin-C and Creatinin Based GFR: is Increasing GFR Reflected Hyperfiltration and Possible Renal Damage in Future?

Salman Dilsah Onerli , Siklar Zeynep , Ilarslan Nisa Eda Cullas , Kocaay Pinar , Ozcakar Birsin , Berberoglu Merih

Introduction: There is a growing interest in the relationship between obesity and renal damage. Chronic kidney disease is accepted as an important complication of obesity in adulthood. However, information on association between childhood obesity and renal functions is limited. In this study, It is aimed to investigate the renal functions in obese children and adolescents.Patients and methods: We enrolled 107 obese children and adolescents as a study gro...

Evaluating First Year Response and Final Height to Growth Hormone Treatment in Growth Hormone Deficiency Based on Peak GH Levels on Testing

Abali Saygin , Bas Serpil , Akbarzade Azad , Atay Zeynep , Haliloglu Belma , Guran Tulay , Turan Serap , Bereket Abdullah

Background: Diagnosis of GH deficiency (GHD) is a complicated issue especially in isolated GH deficiency. Auxological evaluation, IGFI, IGFBP3 levels and GH response to provocative testing are all considered in the diagnosis. However, cut-off values for GH levels at stimulation tests are controversial. We aimed to evaluate the response to rhGH treatment in patients with different GH peak levels in stimulation test.Objective: We aimed to evaluate the resp...

Background: Short stature is the most common presenting symptom in Turner Syndrome (TS). GH treatment helps alleviating short stature in TS, although response to treatment varies significantly.Objective and hypotheses: We aimed to evaluate the response to GH treatment and factors affecting this response in children with TS.Method: Forty-nine patients with TS diagnosed by cytogenetic analysis and who had been followed minimum of 1-y...

Thyroid hormone resistance syndrome due to a new mutation in the TRHA gene

Tuhan Hale , Donbaloğlu Zeynep , Kırbıyık Özgür , Parlak Mesut , Demir Korcan

Introduction: Resistance to thyroid hormones is defined as lack of response of peripheral tissues to triiodothyronine (T3) which is the active form of thyroid hormones. In general (85%) a mutation is detected in the thyroid hormone receptor β (THRB) gene and more rarely, the thyroid hormone receptor α (TRHA) gene.Case: A 4.7-year-old boy, was admitted to the pediatric endocrinology outpatient clinic of Akdeniz...

Evaluation of Copeptin Level in Children and Adolescents Monitored with Central Diabetes Incipidus

Manav Mustafa , Ozsu Elif , Dogan Ozlem , Siklar Zeynep , Kizilcan Cetin Sirmen , Aycan Zehra , Berberoglu Merih

Background: Polyuria-polydipsia syndrome (PPS) is a common condition in children, and its etiology is not always easily elucidated. Although the water deprivation test remains the gold standard for diagnosis, its limitations necessitate the search for alternative diagnostic methods. Due to its stability, copeptin is a valuable current parameter that is considered more reliable than AVP measurement. This study aims to compare copeptin levels between patients wi...

Can asprosin be used as a diagnostic biomarker for non-alcoholic fatty liver disease in obese children?

Tuhan Hale , Singin Berna , Donbaloğlu Zeynep , Özdem Sebahat , Parlak Mesut

Objective: As obesity rates rise among children, non-alcholic fatty liver disease (NAFLD) is becoming more prevalent. Although liver biopsy is considered the gold standard for diagnosing NAFLD, it is an invasive procedure and not practical for screening. Asprosin, a recently unveiled adipokine, is released in response to fasting. In this study, we aim ed to investigate the diagnostic value of asprosin for NAFLD in obese patients....

Comparison of Steroid Hormone Levels Measured by Immunoassay and Liquid Chromatography-Mass Spectrometry (LC-MS) Methods in the Follow-Up of Patients with Congenital Adrenal Hyperplasia

Taba-Tabai Shahla , Ozsu Elif , Siklar Zeynep , Kizilcan Cetin Sirmen , Dogan Ozlem , Aycan Zehra , Berberoglu Merih

Background: Congenital adrenal hyperplasia (CAH) is an autosomal recessive inherited disorder resulting from a genetic defect in one of the enzymes involved in the synthesis of cortisol from cholesterol in the adrenal cortex. Although steroid hormone levels are used in the diagnosis and monitoring of CAH, not all steroid hormone levels can be measured by ELISA. Steroid hormone levels are measured using immunoassay and liquid chromatography-mass spectrometry (L...

Evaluation of the growth response of children with growth hormone deficiency according to peak growth hormone levels on provocative tests

Donbaloğlu Zeynep , Singin Berna , Acar Sezer , Bedel Aynur , Barsal Çetiner Ebru , Aydin Behram Bilge , Parlak Mesut , Tuhan Hale

Objective: We aimed to evaluate the relation between the peak growth hormone (GH) levels on provocative tests and response to recombinant human GH (rhGH) therapy in patients with GH deficiency (GHD).Methods: This was a cross-sectional, single-center, and retrospective study. A total of 518 patients who received rhGH therapy under the age of 16 in the Endocrinology Clinic of Akdeniz University Hospital between 1997 and 20...

Objective: We aimed to examine the auxological findings of the girls diagnosed with idiopathic central precocious puberty (CPP) at the end of the Gonadotropin-releasing hormone analogs (GnRHa) treatment and to investigate the effect of related factors on the height gain of those patients.Methods: This study was designed as single-center, descriptive, cross-sectional retrospective study. A total of 43 patients who were di...
